3 Claims.

This invention appertains to new and useful improvements in mowers such as are used for mowing grass and more particularly. to a mower of the reciprocating sickle type. a

The principal object of the present invention is to provide arnower which will cut growths which could not be cut by the usual revolving blade-type of mower now in general use.

Another important object of the invention is to provide a mower which can be readily adjusted and wherein the parts are so constructed and arranged as to permit ready repair and replacement of parts.

Other objects and advantages of the invention will become apparent to the reader of the follow- In the drawings:

Figure 1 represents a top plan view.

-Figure 2 is a section on the line 2-2 of Fi ure 1. I

Figure 3 is an end elevational view of the mower with a portion in section.

, Figure 4 is a fragmentary top plan view of the sickle blade.

Figure 5 is a fragmentary detailed sectional view on the line 5-5 of Figure 2.

Figure 6 is a fragmentary detailed sectional view on the line 6-8 of Figure 5."

Figure '7 is a fragmentary top plan view of the sickle structure.

Figure 8 is a fragmentary detailed sectional view on the line 8-8 of Figure 1.

1 Figure 9 is a sectional view taken substantially on the line 8-9 of Figure 3.

Referring to the drawings wherein like numerals designate like parts, it can-be seen that the mower consists of the round riding wheels 5-8 mounted on the stub shafts 8 which project downwardly from the frame plates 1-1. These frame plates 1-! are braced by the tie rods, 8, 9 and I0.

Numeral l I represents the handle bar from the lower end of which the brace legs I2l2 extend or-fiuted wheel l8. the peripheral portion of which rides within the confines of the upstanding arms a-a of the Y-shaped yoke l3, this yoke having the depending shank 20 which is rotatably disposed into the socket 2|, the latter being secured by gears 22 and securing elements 23 to the sickle blade 24. The inner sides of the arms 0-0; of the yoke i9 are recessed to receive the ball bearings 25. These ball bearings ride against the opposite sides of the fluted wheel It.

The sickle structure is generally referred to by numeral 26 and consists of the elongated guard bar 21 having the guard teeth 28 extending forwardly therefrom. Above the guard bar 21 is the top bar 29 which is slotted as at 30 so that the socket 2! can extend upwardly therethrough and be permitted to travel longitudinally of said bar 29.

A set screw 3| is feedable downwardly through each end portion of the bar 29, the lower end of the set screw being recessed to receive a ball bearing which rides against the sickle blade 24, this ball 32 being seated in 'a longitudinally extending groove 33 of said sickle blade 28.

Each end of the guard bar 21 is provided with ground and maintain the sickle at the proper cutting elevation.

Rearwardly tapering blade structures 42, having their forward end portions somewhat feathered as at 83 are each sharpened on its forward end portion and onits lower edge portion for the purpose of cutting grass along walks or paths.

A member 44 and the aforementioned bolt 81 serves to secure each blade 42 to the corresponding shoe 40. j

It'can now be seen, that rotation of the wheels 5 will drive the fluted wheel l8 in the fluted or waved edge portion of the wheel, in acting against the ball bearings 25-25 of the yoke i8 reciprocate the sickle blade and result in the necessary cutting-operations. .The blades 42 will 'serve to out along walks and will define the path cut by the mower in general and the inwardly struck tongue portions 45 will serve to guide blades of grass and other growths into the space between the first adjacent pair of cutter guard teeth.

It can further be seen numeral 48 repre sents a guard in the form of an elongated metallic strip which has one end secured as at M to the brace arm W for the guard bar 21, while the forward end of the guard 48 passes over the wheel 5 l8 and then downwardly and is secured by a set screw 49 to the top bar 29 of the sickle assembly. 'Side arms 48a furnish additional supporting means for the bar 21.

While the foregoing specification sets forth m the invention in specific terms, it is to be understood that numerous changes in the shape, size andmaterials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter. 15 Having described the invention, what is claimed as new is:

v1. A mower comprising a pair of drive wheels, a shaft disposed'between the drive wheels and in driven relation with the drive wheels, a fluted 0 wheel on the driven shaft, 2. sickle bar, said sickle bar being provided with an upstanding yoke adapted to straddle the edge portion of the said fluted wheel, said mower including a frame, brace bars between the end portions of the frame, 25 said-sickle bar including a guard bar, and an arm extending rearwardly from the guard bar and having its rear end swingably connected to one of the said brace bars.

2. A mower comprising. a pair of wheels, a shaft interposed between the wheels and being in driven relation with the wheels, a fluted wheel carried by the driven shaft, a sickle structure disposed with its end portions terminating in front 6 V l' of the said wheels, said sickle structure including a sickle blade driven by the fluted wheel, and end cutter blades carried by the ends or the sickle structure, the ends of the said sickle structure being provided with vertically adjustable ground 10 riding shoes, said end cutter blades being secured to the said shoes and adapted to project forward- 1y therefrom and provided with sharpened forward and bottom edges.

3. A mower comprising a pair of wheels, a

shaft interposed between the wheels and being in driven relation with the wheels, a fluted wheel carried by the driven shaft, a sickle structure disposed with its end portions terminating iii front of the said wheels, said sickle structure including a sickle blade driven by the fluted wheel, and end cutter blades carried by the ends of the sickle structure, the ends of the said sickle structure being provided with vertically adjustable ground riding shoes, and inwardly disposed deflectors on the cutter blades for deflecting adjacent blades oi grass inwardly toward the sickle structure.
